ABSTRACT
Methane and air enter a reactor (at 1F, 1A, Figure P.17.2) with an equivalence ratio of 0.8. A fraction of the exhaust gas is withdrawn at station 4 and mixed with the incoming mixture at station 3. If the exhaust gas recirculation fraction is (FGR) of the product gases, derive an expression for O
% in the exhaust (station 5). What will equilibrium NO be for such a scheme if the inlet temperature is 298 K and 10% excess air are used?
